Multiple parietal reach regions in humans: cortical representations for visual and proprioceptive feedback during on-line reaching [PDF]

open access: yes, 2009
Reaching toward a visual target involves at least two sources of information. One is the visual feedback from the hand as it approaches the target.

Continuous Adaptive Finite Reaching Time Control and Second-Order Sliding modes [PDF]

open access: yes, 2013
This paper focuses on the design of adaptive finite reaching time control for first- and second-order dynamic systems with perturbation terms given in a regressive form. The uncertainties considered here are assumed to be bounded with unknown bounds. The

Coding of reaching in 3-D space [PDF]

open access: yes, 2013
Many psychophysical studies suggest that target depth and direction during reaches are processed independently, but the neurophysiological support to this view is so far limited.

Visually guided reaching depends on motion area MT [PDF]

open access: yes, 2007
Visual information is crucial for goal-directed reaching. A number of studies have recently shown that motion in particular is an important source of information for the visuornotor system.

Physical demand but not dexterity is associated with motor flexibility during rapid reaching in healthy young adults [PDF]

open access: yes, 2015
Healthy humans are able to place light and heavy objects in small and large target locations with remarkable accuracy. Here we examine how dexterity demand and physical demand affect flexibility in joint coordination and end-effector kinematics when ...

Stimulus-Response Compatibility effect in the near-far dimension: A developmental study

open access: yesFrontiers in Psychology, 2016
The present study investigates the developmental aspect of stimulus-response compatibility effect in 8 to 11-years-old children. The task consisted in manually responding to the colour of a pawn presented on a chessboard at different distances.

An investigation of the neural circuits underlying reaching and reach-to-grasp movements: from planning to execution.

open access: yesFrontiers in Human Neuroscience, 2014
Experimental evidence suggests the existence of a sophisticated brain circuit specifically dedicated to reach-to-grasp planning and execution, both in human and non human primates (Castiello, 2005).

Mini-max feedback control as a computational theory of sensorimotor control in the presence of structural uncertainty

open access: yesFrontiers in Computational Neuroscience, 2014
We propose a mini-max feedback control (MMFC) model as a robust approach to human motor control under conditions of uncertain dynamics, such as structural uncertainty. The MMFC model is an expansion of the optimal feedback control (OFC) model.
